The camshaft position sensor helps the engine control unit sync the firing of the spark plugs with the position of the pistons. If this sensor fails, it can cause the engine to run roughly or misfire.
In this article, we’ll take a look at the most common symptoms of a bad camshaft position sensor.

How Does The Camshaft Position Sensor Work?
The camshaft position sensor is located in the engine and monitors the position of the camshaft. It sends a signal to the computer to control the ignition timing and fuel injection.
The camshaft position sensor is usually located near the crankshaft position sensor. It consists of a magnet and a Hall effect sensor. As the camshaft turns, the magnet spins past the sensor, producing a voltage pulse. This pulse is then sent to the computer, which uses it to determine the position of the camshaft.
In some engines, the camshaft position sensor is also used to monitor valve timing. If the sensor fails, it can cause engine misfires, reduced fuel economy, and difficulty starting the engine.
The camshaft position sensor is an important part of the engine management system and helps to ensure that the engine runs smoothly.
Where Is The Camshaft Position Sensor Located?
The camshaft position sensor is located at the back of the engine, behind the timing belt cover. It consists of a metal plate with a hole in the center, through which the camshaft extends. The sensor is mounted on the engine block, and its purpose is to monitor the position of the camshaft as it rotates.
How Many Camshaft Position Sensors Are In A Car?
Most modern cars have four camshaft position sensors: two for the engine’s intake valves and two for the exhaust valves.
What Are the Symptoms of a Bad Camshaft Position Sensor?
A bad camshaft position sensor can cause a host of problems with your car.
The most common symptom is an engine that stalls or doesn’t start. You may also notice that the engine is running rough, has decreased power, or is misfiring. In some cases, you may get a check engine light or other diagnostic trouble code.
If you suspect your camshaft position sensor is going bad, it’s important to get it checked out as soon as possible. A faulty sensor can cause serious engine damage if not fixed quickly.
How To Test The Camshaft Position Sensor?
To test the camshaft position sensor, you’ll need a digital multimeter.
Start by disconnecting the negative battery terminal to avoid any electrical damage. Once the battery is disconnected, locate the camshaft position sensor and unplug it.
Plug your multimeter into the two exposed wires on the sensor. Set your multimeter to the “resistance” setting and touch the probes to the wires. You should see a reading of approximately 1,000 ohms. If you don’t get a reading or if the reading is significantly different, then the sensor needs to be replaced.
Reconnect the negative battery terminal and start the engine to test the new sensor. If everything is working properly, you should see a noticeable improvement in performance.
Can The Camshaft Position Sensor Cause A Misfire?
The camshaft position sensor is located in the engine and relays information about the position of the camshaft to the computer. This information is used to control ignition timing and fuel injection. If the sensor is faulty, it can cause the spark plugs to fire either too early or too late, resulting in a misfire.
In some cases, the check engine light will come on if there is a problem with the camshaft position sensor. If you are having problems with your engine misfiring, it is worth checking the camshaft position sensor to see if it is the cause.
Can You Clean The Camshaft Position Sensor?
It may be possible to clean the sensor if it is covered in dirt or oil. However, if the sensor is damaged, it will need to be replaced.
The best way to clean the sensor is to remove it and soak it in a solution of water and vinegar. Then, use a soft brush to remove any build-up on the sensor. You can also try using a can of compressed air to blow any dirt out of the sensor. If the sensor is still not working after you’ve cleaned it, you may need to replace it.
You can also try cleaning the connector with an electrical connector cleaner.
How To Replace A Camshaft Position Sensor?
First, locate the camshaft position sensor. It is usually located near the top of the engine, behind the timing belt cover.
Once you have found it, disconnect the electrical connector and remove the retaining bolts with a wrench.
Then, take out the old sensor and install the new one in its place. Be sure to tighten the retaining bolts at the right spec. Reconnect the electrical connector before starting the engine.
With a new Camshaft Position Sensor installed, your engine should run smoothly once again.
